Abstract

The issue of items that are not independent, not linear, do not have value accuracy and missing data errors, thus the research aims to test the analysis of the construct validity of the self-efficacy instrument, the research uses a quantitative approach with a cross sectional survey design, then the validity analysis uses the Rasch model with the Winsteps version 3.73 application. The results of this study are (1) all items of the Self-efficacy revealing instrument meet the standard criteria as a measuring instrument. (2) Cronbach Alpha as a measure of the interaction between the person and the item as a whole, has a value that is included in the good category. (3) Person Reliability as an indicator of the constancy of respondents' answers, the results of its value are included in the sufficient category. While (4) Item Reliability as an indicator of the quality of items on the instrument, its value is included in the excellent category. (5) The average difficulty level of items is below the ability of junior high school students, so it is easy to understand. The instrument can be used as a need assessment for students in measuring self-efficacy ability curately

Abstract

This study was conducted to analyse the validity of the self determination instrument. The study used a quantitative approach with a cross-sectional survey design with a convenience sample technique of 102 people, consisting of 45 men and 57 women, in junior high schools in West Java, Indonesia. The self-determination instrument was elaborated from Ryan and Deci's Theory, with 17 items and 6 levels of answer choices. Data were analysed using the Rasch Model with the help of Winstep software version 3.73. Analysis of self-determination instrument results through the Rasch model based on aspects of unidimensionality, item analysis (item difficulty level and item suitability level), diagnostic rating scale and instrument analysis. The results of the reliability value of 0.91 so that it can be used as a consideration of measuring instruments to measure self-determination abilities in junior high school students, and the Guidance and Counselling process can be implemented in the need assessment step.
